bugimäärien

Bugmäärien, or bug counts, are a basic metric in software engineering that records the number of defects identified in a software product during development, testing, and use. They are tracked in issue trackers and often summarized per release, module, or testing phase. Bug counts serve as a rough indicator of software quality and stability, complementing other measurements such as test coverage and performance metrics.

Common related metrics include open versus closed defects, new defects discovered in a given period, and reopened defects. More refined measures include defect density (the number of defects per thousand lines of code or per function point) and severity- or priority-weighted counts. Trends in bug counts help teams evaluate testing effectiveness and risk exposure.

Bug counts are influenced by many factors beyond code quality, such as testing scope, tool support, and the clarity of requirements. Duplicates, misclassified defects, and differences in severity definitions can distort the numbers. Therefore, bug counts are most useful when standardized definitions and consistent triage processes are applied across projects and releases.

In practice, teams use bug counts alongside other quality indicators, including test coverage, defect aging, mean time to repair, and customer-reported issues. They contribute to release readiness decisions and resource planning but should not be interpreted in isolation. Context, trend over time, and normalization matter for meaningful insights.
